Hillcrest fire cause said electrical

HILLCREST  Electrical equipment sparked a blaze that damaged a medical building in Hillcrest early Tuesday.

The fire on Fourth Avenue north of Walnut Avenue was discovered about 12:20 a.m., a San Diego Fire-Rescue Department dispatcher said.

Firefighters found the building surrounded by thick smoke, with flames coming from some electrical equipment outside one wall. They got most of the fire out within 20 minutes, then tore apart some of the wall to make sure it was fully extinguished.

The building originally was a home, converted to a medical building, fire spokesman Lee Swanson said.
